The Common Goldeneye spends part of its year on freshwater lakes, and part on the coastal ocean. Like other sea ducks, they have an adaptation that allows them to drink saltwater safely.

Global trade is dominated by ocean transport, but along with goods and commodities ships may also transport biological invaders. Managing ballast water to protect ecosystems and ports from these alien stowaways is a critical tool.

A watershed is where rainwater and snowmelt collects and flows to the ocean. As the water flows down streams and rivers, it carries along part of what it touches, from sand and rocks to trash and pollution. A new Aquarium exhibit shows how a local watershed works.

Mangrove forests are a feature of tropical coastlines. In addition to protecting shorelines from erosion and waves, they support a thriving population of fish and invertebrates. The loss of mangrove forests to deforestation and development bodes poorly for shoreline protection and fisheries.

The Gulf of California is home to a diverse assemblage of wildlife. This diversity is a reflection of the Gulf's distinctive geography. Impacts to wildlife from a variety of sources threaten many of the rare and endangered species that make the Gulf their home.

Surgeonfish are colorful members of coral reef communities throughout the tropical Pacific Ocean, popular with divers and aquarists. Their brilliant colors are a warning to potential predators of their sharp defenses.

As kids head back to classes this September, they aren't the only ones in school. Most species of fish form large aggregations called "schools" as well. The reasons why range from safety in numbers to finding food more easily to saving energy while swimming.

Seabirds nest in remote rookeries, often on high cliffs. Their eggs are adapted to survive the sometimes harsh, highly vertical environment where the birds nest.

Check out our "kid friendly" podcast that's all about sharks! This exclusive podcast includes terms that people of all ages can understand. You'll learn how sharks use their senses of hearing, smell, touch, taste, and sight. They also have a sixth sense, the ability to sense electricity.

During the summer months above the Arctic Circle, the sun may stay above the horizon for up to weeks or months. Wildlife at these latitudes adapt to the absence of night.
